Important new research has shown that commonly used food dyes, such as Yellow 5, Red 40, and six others, are linked to hyperactivity, impulsivity, learning difficulties, and Attention Deficity Hyperactivity Disorder in many children. The Center for Science in the Public Interest has petitioned the Food and Drug Administration to ban the use of these dyes, many of which are already being phased out in Europe.

These dyes—petrochemicals, mostly—are often used to simulate the presence of healthy, colorful fruits and vegetables. But considering the adverse impact of these chemicals on children, and considering how easily they can be replaced with colorings derived from real food ingredients, it’s time to get rid of them altogether.
